Overview

AI-generated overview

Read-only FET112 server giving assistants signed Ethereum security reports and native Fetch network metrics with verifiable attestations.

What you can do
  • Fetch signed Ethereum security context: current SecurityReportV1, network status verdict, recent incidents, and a deterministic pre-action check
  • Verify attestations offline, including arbitrary report/attestation pairs and quantitative context against a trusted key fingerprint
  • Discover signing keys and fingerprints for the service
  • Query native fetchhub-4 analytics: catalog of metrics, validated read-only queries, transaction activity, today-versus-yesterday comparison, and staking flow
  • Attest and verify observed network state for the latest finalized hour
When to use it
Useful when an assistant needs to check Ethereum security context before acting on Fetch/ASI contracts, or wants signed, verifiable Fetch network activity and staking metrics rather than raw chain queries. The attestation and verification tools suit workflows that must show data provenance and freshness.
Requirements
A remote streamable HTTP endpoint; no authentication, environment variables or headers are declared. Network access to the provider is needed. Verification against a trusted key fingerprint requires that fingerprint to be supplied by the caller.
Before you install
Security verdicts apply only to configured Fetch/ASI contracts on Ethereum (chain_id=1) and must not be applied to native fetchhub-4 traffic. The pre-action check does not classify destination, amount, asset or authorization and does not simulate transactions. Key discovery is not an independent trust anchor, and NOT_EVALUATED means no assessment was made. Data is read-only and public.

Installation

In SourceWeft

  1. Open FET112 in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.fet112%2Ffet112/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

fet112.network_state_attestation

Native Fetch state attestation

Attest observed native fetchhub-4 gas, transactions and blocks for the latest available finalized hour (four 15-minute windows). Signed coverage, source cursor, issue/expiry times and explicit fresh/stale/partial/unavailable observation status. No Ethereum data, native security verdict, anomaly assessment or live chain RPC. Optional content_hash retrieves an exact retained document; archive is process-local (up to 128 documents, one hour, lost at restart).

Parameterscontent_hash

fet112.verify_network_state_attestation

Verify native state attestation

Verify canonical signed payload, pinned identity, expiry and source age independently. No live chain canonicality check.

Parametersdocumentrequiredtrusted_key_fingerprint

fet112.network_state_keys

Native state signing key discovery

Discover current Ed25519 public key and fingerprint. Discovery is not an independent trust anchor.

Takes no parameters.

fet112.analytics_catalog

Native analytics capabilities

Discover supported native metrics, exact semantics, aggregations, coverage requirements and executable query examples. No model or chain RPC calls.

Takes no parameters.

fet112.analytics_query

Native analytical query

Execute a validated read-only native Fetch query: sums, extrema, weighted means, groupings, rollups and comparable UTC windows. Read analytics_catalog first. Missing coverage is an error, never zero. Top rankings cannot be combined across buckets. Amount maxima do not identify transaction hashes. Inspect integrity and consumer_policy; no native security or anomaly decision.

fet112.transaction_comparison

Native Fetch Same-Interval Comparison

Compare native fetchhub-4 transactions TODAY and YESTERDAY over exactly the same elapsed UTC interval, ending at today's latest authoritative finalized cutoff. Both windows come from one SQLite snapshot. Returns counts, success rates, exact count difference and percentage change; unavailable coverage returns ErrorV1. No significance test, anomaly decision, cause attribution, forecast or native-chain security assessment. Follow consumer_policy. Inspect integrity.signed and verify the quantitative attestation before claiming verification.

Parametersschema

fet112.verify_quantitative_context

Verify Native Quantitative Context

Verify the separate native quantitative Ed25519 attestation and full consumer policy. Supply a trusted fingerprint to verify identity; does not evaluate chain canonicality, freshness or security.

Parameterscontextrequiredtrusted_key_fingerprint

fet112.transaction_activity

Native Fetch Transactions and Success

Native fetchhub-4 transactions included in blocks for today or yesterday UTC. Returns successful/failed/total counts, success percentage and average TPS over contiguous finalized 15-minute buckets. Empty periods with valid coverage have zero TPS and a NOT_APPLICABLE/null success percentage. Missing evidence returns an error, never zero activity. Not peak TPS, capacity, messages, or mempool attempts. Signature status is explicit in integrity.signed; no statistical anomaly or security verdict. Default: today.

Parametersperiodschema

fet112.staking_context

Native Fetch Staking Flow

Observed native Fetch staking FLOW on fetchhub-4 for today or yesterday UTC, using finalized 15-minute buckets and comparable historical periods. Returns exact afet strings, coverage and source cursor. This is NOT total staked balance, a statistical anomaly assessment, or a security verdict. Signature status is explicit in integrity.signed. Errors mean unavailable evidence, never zero flow. Defaults: today, 7 baseline days.

Parametersperiodschemabaseline_days

fet112.network_status

FET112 Network Status

Return FET112's current machine-facing network status. The verdict is copied from SecurityReportV1 for configured Fetch/ASI contracts on Ethereum (chain_id=1). Do not apply it to native fetchhub-4 traffic.

Takes no parameters.

fet112.recent_incidents

FET112 Recent Incidents

Return bounded recent incidents associated with the current signed report context.

Parameterslimitcursorseveritysince_height

fet112.security_report

FET112 Signed Security Report

Return the current signed SecurityReportV1 for configured Fetch/ASI contracts on Ethereum (chain_id=1). It does not evaluate native fetchhub-4 traffic.

Takes no parameters.

fet112.pre_action_check

FET112 Pre-Action Check

Deterministic pre-flight over the current watched Ethereum security environment. V1 commits the intended action but does not classify destination, amount, asset, business authorization or simulate the transaction.

Parametersassetrequiredactionrequiredamountrequiredmetadatadestinationrequired

fet112.verify_attestation

Verify FET112 Attestation

Verify an arbitrary SecurityReportV1/attestation pair offline, optionally against a trusted FET112 key fingerprint.
